晶間裂紋 的英文怎麼說
中文拼音 [jīngjiānlièwén]
晶間裂紋
英文
intercrystalline cracking-
It is found that the nano material is distributed not only among general material grains to form inter - granular structure of the coating but also in the general material grains to form intra - granular structure. micro - crack caused by laser will be eliminated greatly. 3 mechanical performances of the ceramic coating manufactured are tested
得到的結論是經過激光熔覆后的塗層緻密化程度有了很大的提高，比單純的激光重熔塗層還高，納米顆粒不僅填充在晶粒之間，而且還嵌入在大晶粒內部，有利於消除激光作用產生的微裂紋。Geological material, no matter soil or rocks, has the characteristic, such as crystal grain structures, pores or micro - cracks etc., on micro - scale and usually contains fluid or gas in pores and micro - cracks. so the problems about geological material are really the problem of the interaction between the fluid, solid and gas
地質材料，不論是土還是巖石，在微觀結構上都具有晶粒結構、孔隙、微裂紋等特徵，並且在孔隙或微裂紋中還往往含有流體或氣體，因此地質材料的力學問題往往是液體、固體以及氣體間相互作用的問題。By the analyses of corrosive medium and manufacturing process quality, the cracks of glycol evaporators in dushanzi petrochemical company have been confirmed to be intergranular corrosion cracks
摘要通過裂紋宏微觀形貌分析、腐蝕介質分析、對蒸發塔製造過程質量分析等，證實了獨山子石化乙二醇蒸發塔的裂紋屬晶間型應力腐蝕裂紋。The flexural strength and fracture toughness of ti3sic2 material obtained by hot - pressing is 223mpa and 5. 1 mpa m1 / 2 respectively ; the mechanisms of grain bending, grain delamination, crack deflection inside the layered grain, crack deflection and branch, pull out grain are main energy absorbing mechanisms
~ 1ti _ 3sic _ 2材料的彎曲強度和斷裂韌性分別為223mpa和5 . 1mpa ? m ~ （ 1 / 2 ） 。主要能量吸收機制為：晶粒的彎曲、層間滑移，裂紋在層間擴展與偏轉，裂紋在晶粒間沿晶界擴展、分叉和晶粒的拔出。Taking in - situ toughened silicon nitride as a design object, principle component analysis ( pca ) is applied to study the microstructure and mechanical properties, to find out the main microstructure controlling factors, and to simplify the characterization variables and criterions ; fuzzy neural networks ( fnns ) is also applied to develop a design expert system for this material, which can realize the forward prediction from processing, microstructure to mechanical properties, and backward design from mechanical properties or microstructure to processing ; monte - carlo method is applied to simulate the grain growth of this material, and then crack propagation is simulated, which is another way based on physics and chemistry to developing prediction models from processing until to mechanical properties
本文以自增韌氮化硅陶瓷為設計對象，運用主成分分析法（ principlecomponentanalysis ： pca ）對自增韌si _ 3n _ 4陶瓷的顯微結構和力學性能進行數據空間降維，獲得自增韌si _ 3n _ 4陶瓷顯微結構控制的主要因素，進而簡化了表徵參量變量和準則；運用模糊神經網路（ fuzzyneuralnetworks ： fnn ）建立了自增韌si _ 3n _ 4陶瓷設計專家系統，能實現工藝?微結構?性能的正向預測及反向設計；運用monte - carlo方法（ mc ）進行自增韌si _ 3n _ 4陶瓷的晶體生長模擬，然後進行裂紋擴展模擬，探索建立工藝?微結構?力學性能預測模型的思路。分享友人
